So there's the lens that pops out of the camera when I turn it on, and inside it theres something of glass like a lightbulb.

Inside that thing is the sensor or the thing that takes the photos.

I need to clean the lightbulb thing because it is dirty and it is annoying on my photos ..

How could I do that?

Me. I'd use a qtip and 90% alchohol. Then let it dry for a day.

I'm a bit puzzled by your description but:

• A tube that 'telescopes' out, in one or more sections ought to carry the lens glasses
• I think that you mean the front (exposed) element; you could mean a surface that not exposed and that is always going to be harder, because it is not exposed, but the same thing makes them less likely to get dirty

(The lens elements are often called 'glasses', although, these days, they are often plastic rather than glass, depending on the type of camera and technology. That makes things more difficult, because some solvents are compatible with glass and the coatings but are not compatible with plastics materials.)

Be very careful about this suggestion; most samples of isopropyl alchohol do not dry completely clean, and if you use something that does not dry completely clean, you'll get a general coating which will dull your photos and reduce definition. Additionally, you may just spread the existing rubbish around. Now this might be slightly less annoying than noticeable 'lumps' on the photos, but you'll be trading one very apparent problem for a different slightly less annoying one.

There are some lens cleaning products that put down a layer of a 'cling film'-like plastic, which you can then peel off, and which brings the pollution with it. I've used this kind of thing on secondhand (glass) lenses before now, and they seem to work well. If your lens has a plastic element that you want to clean, you would need to look at the product information sheet to check that it is compatible. Someone at a good photo shop (if they still exist where you are) ought to be able to help.

Of course, the best advice is not to let the lens get dirty in the first place, but while you can't apply that advice now, maybe you'll be able to if you get your lens clean.

I think I didn't really describe my problem very well..

It's not one of those huge cameras ..

So I don't even know how to get past the external lens to get to the little stuff inside the cam.

I think it's the protector for the CCD that I want to clean.

PS: If there's the chance that I get the whole thing dirty , then I'll just leave it as it is, it's not that bad after all , but I thought it would be a good idea to clean it..

That seems to imply that the bad stuff is not on the external surface. That makes it difficult, if you can't easily disassemble and reassemble the lens. Also, be aware that you have to align the lens elements correctly (if you remove them), or that can also severely limit lens performance.

The 'CCD protector' may be an explicit dust screen, or it may be the 'Bayer filter', which separates out the Red, Green and Blue light. Misaligning the Bayer filter could be horrible, so be very careful if it seems to be the case that the Bayer is part of the problem.

If you take it to a professional Photographic Repairer, they'll probably quote you more than the value of the camera. That might make you feel that you have relatively little to loose if you try something and it ruins the camera, because replacing the camera will cost less than a repair, I don't know.
